Question

强文本根据 Google 的指南，不建议在应用加载或退出时展示广告。

您从 onBackPressed 中删除此代码并将其添加到 onClick 处理程序中。

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        ...

        final Button myButton = ..
        myButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (interstitial.isLoaded()) {
                    interstitial.show();
                }
            }
        }
    }
